UNITED STATES .PATENT OEEncE!o y JOHN HENDERSON, OF HORSEHEADS, NEW YORK.

IMPROVEMENT IN HUB AND AXLE FASTENINGS.

Specification forming part of Letters Patent No. 12,946, dated May 29, 1855.

To all 'whom it may concern:

Be it known that I, JOHN HENDERSON, ol

-Horseheadsg in the county of Ghemung and State of New York, have invented a new and Improved Method of Fastening Wheels to Oarriages; and I do hereby declare the following to be a full, clear-,and exact description thereof, reference being had-to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a. section of the llllb and fastening.

. A is the axle, having a grooved neck turned Aupon it at B. C and D are the upper and lower parts of the frustum-bax fastening, ill which the peculiarityof my invention chieliy consists. E is the cap,whch screws on the box F ofthe hub G and completes the fastening. The fastenin g is a frustuln-shaped box divided into two nearly equal parts, as shown at Fig 2, by all irregular line from a to b, and a portion removed at c. The neck of the axle is dropped into a. hollow in the base or larger end ot' the lower section, as at Fig. 4, where the upper section is placed in its proper position and the cap E, Fig. 1, is screwed on,-the two parts of the box being firmly coln pressed by it, and rendering the fasteningl secure until the cap is againtremoved, and forming a tight receptacle for oil or grease, and completely excluding dust, 85e., from ventering the axle-box. The upper and lower parts o f the box are divided in such a manner as to permit the lower one to slide forward sufficiently to' connect or disconnect with the axle, Figs. 4 and 5, without removing the other part from the cap, which may be either fastened to the cap immovably, as ill the model, or secured by a pill and slot, so as to slide a part of the way out of the cap and facilitate its connection with the axle. K

The construction of the frustum-box is shown ill various positions in Figs. 2,3, 4, and 5, and its positionto the axle, hub, and cap in Fig. 1.

'What I claim as lny invention', and desire to secure by Letter' Patent, is-

The peculiar form ot' t-he frustunrbox fastening, operating in the lnanneralld for the purpose herein described.

JOHN HENDERSON.
